Application filed September 13. 1901. Serial No. 75,258. (No inodcl Bc it known tnatl, .Luiss ifo-11; nu n.' .hc "wiwi itatcs. .uni L est nostra, 1n the county or Wanne-na .Y 5,' of Wisconsin, have invented certain new and Utiel l1] lin pl'ovelnentsin Compressed-Air Conn trolling Devices for SandDiscl1argers 5 and I do hereby declare that the following is a full,

clear, and exact description thereof.

1o My invention relates particularly to an at tachment for use in admitting air to a sanddischarging device employed in connection with the engineers brake-valve of a railwaylocomotive; and it consists in certain pecui 5 liarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accompanying drawings and subsequently claimed.

In the said drawings, Figure l is a plan zo view of an enginecrs b aire-valve having attached thereto a device embodying my said` invention, partlyin section on the line l 1 of Fig. 2, showing the parts in position with the air Wholly cnt off from the pipe leading to the 2 5 sand-discharge device. Fig. 2 is a transverse vertical sectional view, taken on the line 2 2 of Fig. l, with the brake-valve handle swung one-quarter around to admit air to the pipe leading to the sand-discharging device and 3o with portions shown in section on the line 2" 2 of Fig. l. Fig. 3 is a detail vertical 1mtional view "alvmeasii 1 taken on .nc .lne e o or fr l. .t detail elevation of the Valve-casing and the 35 operating-levers and attachments comprising the essential parts of my said invention, and Fig. 5 is a detail sectional View on the line 5 5 of Fig. 2.

Referring to the drawings, a represents the i] :il-lil )01E it U1@ YOKC- i ne said ,innere .llLll Q. UppQFSlll'fLC@ 1S LOl'lllCLl ull lill Lllllllllil plilil'x as Shown best in Figs. 2 and 5, for the purpose hereinafter described. The brake-valve handle is provided with the usual spring t, secured to and passing through a slot in the handleshank for engagement with the lugs jjj on the valve-casing iu the usual manner, this bein g old and Well known in brake-valves of this typo, which latter are further connected with the lnainreservoir-pipe 7e. (Shown in Fig. l.) In my invention a pipe m leads from this main pipe 7c to a valve-casing n, having a channel o therethrough, communieating with another pipe p, which leads to tho sand-discharging device, which latter is not shown, and which may be of any ordinary or preferred construction, operated by com pressed air. The channel o is closed by a valve f1, whose stem o' extends vertically up through the vertical passage fr in the upward extension n of the valve-casin g n and through a stu ffmgbox s, screwed to said extension of the easing, and through the suitab1y-paclred nut s of the stuffing-box, said Valve-stem r" being surrounded by a spring t, Within the vertical passage f" in *he "sive-casing exten passage r and @ne said raive-ste1n r is screwthreaded at its upper projecting end for the adjustable reception of a disk u, which when it has been screwed to the desired point is secured in place by a nut n'.

Pivotally secured on a stud m, projecting No. 696,73l. Patented Apr.' l, 19:52.
